  1. 21. Perceptual and Squared Error Aspects in Speech and Audio Coding

    Författare :Harald Pobloth; Bastiaan Kleijn; Gernot Kubin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; speech coding; audio coding; auditory models; perceptual distortion measures; squared error; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. LÄS MER

  3. 22. Generalization under Model Mismatch and Distributed Learning

    Författare :Martin Hellkvist; Ayca Özcelikkale; Anders Ahlén; Martin Jaggi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Signal processing; Generalization error; Training error; Double-descent; Double descent; Distributed learning; Distributed optimization; Learning over networks; Model mismatch; Model misspecification; Fake features; Missing features; linear regression; regularization; Machine learning; Maskininlärning;

    Sammanfattning : Machine learning models are typically configured by minimizing the training error over a given training dataset. On the other hand, the main objective is to obtain models that can generalize, i.e., perform well on data unseen during training. LÄS MER

  4. 23. Node-Level Fault Tolerance for Embedded Real-Time Systems

    Författare :Joakim Aidemark; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; error recovery; reliability calculations; time redundancy; real-time kernels; error detection; analytical coverage estimation; distributed real-time systems;

    Sammanfattning : This thesis deals with cost-effective design and validation of fault tolerant distributed real-time systems. Such systems play an increasingly important role in embedded applications such as automotive and aerospace systems. LÄS MER

  5. 24. Fautes de français

    Författare :Ulla Berling; Elisabet Hammar; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Romance languages - general; error; norm; usage; frequency; distribution; tenacity; interrelation; interlingual; intralingual; homophony; hypercorrection; overgeneralization; Romanska språk - allmänt; Romance languages; Romanska språk;

    Sammanfattning : This empirically based study aims at establishing the frequency, distribution, tenacity and the nature of errors produced by more than 700 advanced Swedish learners of French, at different university levels. The errors are classified in grammatical and lexical categories. LÄS MER

  7. 25. Developing and Evaluating Language Tools for Writers and Learners of Swedish

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interactive learning systems; error; feedback; human-computer interaction; grammar checking; grammaticality judgments; parsing; second language learning; Swedish; evaluation; user studies; language technology; computer assisted language learning; writing; language tools; interaktiva lärsystem; fel; återkoppling; grammatikkontroll; språkverktyg; människa-datorinteraktion; skrivande; andraspråksinlärning; grammatikalitetsbedömning; parsning; Language technology; Språkteknologi;

    Sammanfattning : Skrivande och skrivet språk är idag en viktig del av många människors liv, i datorns ordbehandlare, i e-postprogram och i chattkanaler på Internet. Skrivet språk har blivit mer eller mindre en förutsättning för människors dagliga kommunikation. Denna utveckling av samhället leder till ökade behov av att på olika sätt hantera text. LÄS MER
